Add human notes field for intervention tasks

All tests pass. Let me summarize the implementation:

I've added a human notes field for intervention tasks with the
following

1. **Omni/Task/Core.hs**:
   - Added `retryNotes :: Maybe Text` field to `RetryContext` data type
   - Added `notes` column to `retryContextColumns` for schema migration
   - Updated `getRetryContext` to fetch the notes field from DB -
   Updated `setRetryContext` to save the notes field to DB - Updated
   `getAllRetryContexts` to include notes - Added `updateRetryNotes ::
   Text -> Text -> IO ()` function to updat

2. **Omni/Jr/Web.hs**:
   - Added new API endpoint: `POST /tasks/:id/notes` - Added
   `NotesForm` type and `FromForm` instance - Added `taskNotesHandler`
   to save notes - Updated `renderRetryContextBanner` to accept task
   ID and display:
     - Notes textarea form when max retries exceeded (intervention
     tasks - Existing notes display for non-critical retry banners

3. **Omni/Agent/Worker.hs**:
   - Updated worker prompt to include human notes/guidance in the
   retry - Preserved existing notes when setting new retry context

4. **Omni/Jr.hs**:
   - Updated all `RetryContext` creations to preserve existing notes
